在确定心房是否肥大及那一側心房肥大,对診断心脏病有很大帮助,除了根据临床及胸部X光检查外,心电图为一重要診断心房肥大的方法,过去一般均用P波时間及电压来診断心房是否肥大,Macruz氏等于1958年提出一种以p波及p—R段之比来測定心房是否肥大及为那一个心房肥大。我們在用后觉得这方法确实很好,故在此介紹一下这方法,并将我們使用的結果作一报导。
In determining whether the atrial hypertrophy and hypertrophy on that side of the atrium, the diagnosis of heart disease is very helpful, in addition to clinical and chest X-ray examination, the ECG is an important method to diagnose atrial hypertrophy, the past are generally used P wave time and Voltage to diagnose atrial hypertrophy, Macruz’s equal to 1958 put forward a p-wave and p-R ratio to determine whether the atrium hypertrophy and for that atrial hypertrophy. We think this method is really good after use, so here is a brief introduction of this method and make a report on the results we use.
